What is hydrosphere
The hydrosphere includes all water on, above, and below the Earth's surface, such as oceans, seas, lakes, rivers, streams, groundwater, surface water, and water vapor in the air. It covers 70% of the Earth's surface and provides habitat for many organisms. The hydrosphere consists of oceans, which contain 97% of the planet's water, as well as seas, lakes, rivers, groundwater, and water in the atmosphere.
water vocabulary
Freshwater is water that contains very little salt and is drinkable for humans and wildlife. Freshwater is found in rivers, lakes, streams, water wells, aquifers, waterfalls, and icebergs as well as snow and the polar ice caps. An aquifer is an underground area that is permeable and contains water.

Continental drift
Over 70% of the Earth's surface is covered by oceans, with the remaining 29% comprised of continents. Most continents have their bases in the northern hemisphere and extend southward. Alfred Wegener first proposed the continental drift theory in 1912, suggesting that all landmasses were once joined together in a supercontinent called Pangaea, surrounded by a single ocean called Panthalasa. Pangaea later broke apart into separate continents, including Laurasia and Gondwana, as evidenced by matching coastlines, mountain systems, fossils, and plant and animal distributions between separated lands. The theory of plate tectonics later expanded on drift by explaining the Earth's lithospheric plates that move and interact at boundaries
Water balance calculation
This document presents an overview of water balance calculations. It defines water balance and its components such as precipitation, evapotranspiration, soil moisture, surplus and deficit. It describes different types of water balances including surface water, groundwater, soil water, lake water and oceanic water balances. The document discusses applications of water balance calculations and limitations. It concludes that water balance estimation is an important tool for assessing water resources and supporting water management decisions.
The Earth's Hydrosphere
The hydrosphere is the liquid water component of Earth, including oceans, seas, lakes, rivers, and streams, which collectively cover about 70% of the planet's surface. It is composed primarily of oceans containing 96.5% of Earth's water, while the remaining 3.5% is fresh water found in ice, groundwater, and other sources. The hydrosphere plays a crucial role in regulating climate and provides habitat while also being essential to living organisms and human needs.
Drainage Basins VLE
A drainage basin is the area of land that drains water to a common outlet such as a river or lake. It is delimited from adjacent basins by a watershed divide. A drainage basin can be modeled as an open system with inputs like solar energy and precipitation, stores like glaciers, lakes, soil and vegetation that hold water, and outputs like evaporation and river discharge that remove water from the system. Water and energy from outside sources enter the basin and water leaves through various transfers and outputs.

water resources
Fresh water resources are critical for human and environmental needs. While water covers most of the Earth, only 3% is fresh water. The majority is frozen in glaciers and ice caps, while the remaining unfrozen fresh water exists as groundwater, surface water, or atmospheric water. Groundwater levels are declining in many regions due to excessive human use. Surface water comes from rivers, lakes, and wetlands, but human activities like reservoir construction and wetland drainage have large impacts on water resources. Underground river networks also contribute substantial water flow. Groundwater exists below the ground in soil and rock and is replenished by surface water, but humans can deplete it unsustainably through overuse or pollution. Desalination of
What is hydrosphere?
The hydrosphere includes all liquid water on Earth, such as oceans, seas, lakes, rivers, groundwater, surface water and water vapor in the air. It covers 70% of the Earth's surface. The hydrosphere is home to many plants and animals and includes water in its three main forms: groundwater beneath the Earth's surface, surface water on land and in oceans, seas and lakes, and water vapor in the air.
Power point 2na ii+d
The document discusses the hydrosphere and the global water cycle. It notes that the hydrosphere includes all water on, under, and over the surface of a planet. On Earth, the hydrosphere contains around 1,386 million cubic kilometers of water, with 97.5% being saline ocean water. It also describes the water cycle as the transfer of water between reservoirs like the atmosphere, oceans, lakes, ice caps, and soil. Around 70% of the Earth's surface is covered by water, with the oceans alone containing 96.5% of all water on the planet.
Water Balance VLE
The water balance, or budget, is a simple equation used to understand water resources in a drainage basin. It accounts for precipitation, evapotranspiration, infiltration into soils, storage of water in soils, and outputs like surface runoff and flow into rivers. When precipitation exceeds evapotranspiration, soils become saturated and excess water runs off as overland flow, contributing to rivers. When evapotranspiration is greater than precipitation, stored soil moisture is reduced and depleted.
2 hydrosphere
The hydrosphere includes all water on Earth's surface and subsurface in liquid or frozen form, such as oceans, seas, lakes, rivers and groundwater. It covers 70% of Earth's surface, primarily as oceans, and provides habitat for many organisms. Water cycles between reservoirs in the hydrosphere, atmosphere and geosphere through evaporation, condensation and precipitation in a continuous circular motion.
surface water
Water is essential for life but is often minimal and poor quality for many people. This document outlines issues to consider when planning water supply improvements to select the most appropriate sources. Surface water is water on the planet's surface, like in rivers, lakes, and oceans. It is easily polluted and can flow in streams or remain still in ponds.
The drainage basin
The document discusses the hydrological cycle within a drainage basin. A drainage basin is the area of land drained by a river and its tributaries, forming an open system with inputs, stores, flows, and outputs of water. It instructs the reader to label a diagram of a drainage basin with features including the source, watershed, tributaries, confluence, and mouth.
Hydrosphere
The document summarizes key aspects of Earth's hydrosphere and hydrologic cycle. It describes the hydrosphere as including all of Earth's water found in oceans, glaciers, streams, lakes, soil, groundwater, and air. It also notes that Europa and possibly Ganymede and Enceladus may have subsurface oceans. Additionally, it provides details on the distribution and movement of water between the oceans, atmosphere, biosphere, lithosphere, and the water cycle which traces this movement between stores and spheres.
The water budget
The water budget, or water balance, of a drainage basin shows the relationship between precipitation, evapotranspiration, surface runoff, and changes in water storage. It is often expressed as an equation where precipitation equals surface runoff plus evapotranspiration plus or minus changes in storage. The water budget is useful for hydrologists to understand water surplus and deficit, and to plan for potential water shortages or recharge after deficit. A water budget graph illustrates surplus when precipitation exceeds evapotranspiration and deficit when the reverse is true.
Freshwater
Freshwater is water containing less than 1% salt, including water found on the Earth's surface and underground. There are three types of freshwater: lentic water found in still bodies like ponds and lakes; lotic water in flowing bodies like streams and rivers; and wetlands like swamps and marshes saturated with water. Freshwater covers about 3% of total water on Earth, with about 0.3% as surface water and the rest as ice caps and glaciers or groundwater. Problems affecting freshwater include loss of habitat, pollution, and overuse of resources.
E Science[1]
The document discusses the water cycle and various bodies of water. It describes the water cycle as the continuous movement of water between the earth and atmosphere, involving evaporation, transpiration, precipitation, and collection of water on land or in bodies of water. It also discusses the physical and chemical properties of water, including its chemical makeup of H2O and categories of saline water. Finally, it identifies and describes different types of flowing bodies of water like rivers, creeks, and brooks, as well as non-flowing bodies of water like oceans, lakes, ponds, reservoirs, sloughs, marshes and estuaries.
The hydrosphere
The document discusses the hydrosphere, which is the sphere of water surrounding the Earth. It describes the different components of the hydrosphere, including oceans, seas, rivers, lakes, icebergs, and underground water. Rivers drain the landscape and move water and minerals toward the oceans. Oceans and seas move due to waves, currents, and tides, with currents caused by temperature differences, salinity differences, and wind, and tides caused by gravitational forces from the Sun and Moon.
The drainage basin as a system lesson 2
The drainage basin forms an open system that collects precipitation and drainage from the land. It is defined by high ridges called watersheds and contains a main river and tributaries. Water moves through the drainage basin via various processes, including interception, infiltration, overland flow, throughflow, groundwater flow, and evapotranspiration. The main inputs are precipitation and the main outputs are water flowing into the sea and losses from evapotranspiration.
Earth's Hydrosphere :)
The document discusses Earth's hydrosphere and water pollution. It begins by explaining theories about the formation of Earth's hydrosphere and how much of its water originated from comets and asteroids. It then discusses the history of ice ages and the current ice age. It also describes Europa's subsurface ocean and the possibility of an ocean on Ganymede. The document ends by covering various sources of water pollution including industrial, agricultural, and residential runoff that contaminates water bodies.
Water Distribution on Earth
The document discusses the distribution of water on Earth. It notes that:
- 71% of the Earth's surface is covered in water, but 97% of that water is salty ocean water, leaving only 3% as freshwater.
- The major stores of freshwater are glaciers/ice (2.15%), groundwater (0.61%), and freshwater lakes (0.009%). Smaller amounts are found in the atmosphere, inland seas, soil moisture, and rivers.
- Water is distributed through the hydrologic cycle and, while it changes forms, the amount of water on Earth remains fairly constant over time as it is recycled.

Wei Water Forum - Water Management and Pollution Control through Stakeholder ...Global Water Partnership
The document summarizes the Wei River forums that took place from 2007 to 2009 in Shaanxi Province, China. The forums focused on managing water resources and pollution in the Wei River basin. Key achievements included raising public awareness about water issues, promoting integrated water resource management, and influencing policymakers to approve management plans and strengthen pollution control efforts. Next steps discussed at the 2009 forum involved improving disaster control strategies and developing regulations and systems for integrated management of the Wei River basin.RUNNING WATER AND GROUND WATER
Running water and groundwater are both integral parts of the water cycle. Running water, such as rivers and streams, shapes landscapes through erosion and acts as a resource for energy, industry, and transportation. Groundwater represents the largest accessible freshwater reserve, providing over half of the world's drinking water and a significant portion of its agricultural and industrial needs. It is important to maintain the cleanliness of both surface running water and subsurface groundwater, as water is essential to life and a degraded water supply could create shortages.
Surface water abd ground water
The nation’s surface-water resources—the water in the nation’s rivers, streams, creeks, lakes, and reservoirs—are vitally important to our everyday life. The main uses of surface water include drinking-water and other public uses, irrigation uses, and for use by the thermoelectric-power industry to cool electricity-generating equipment.
Groundwater is an important part of the water cycle. Groundwater is the part of precipitation that seeps down through the soil until it reaches rock material that is saturated with water. Water in the ground is stored in the spaces between rock particles (no, there are no underground rivers or lakes). Groundwater slowly moves underground, generally at a downward angle (because of gravity), and may eventually seep into streams, lakes, and oceans.
Here is a simplified diagram showing how the ground is saturated below the water table (the purple area). The ground above the water table (the pink area) may be wet to a certain degree, but it does not stay saturated. The dirt and rock in this unsaturated zone contain air and some water and support the vegetation on the Earth. The saturated zone below the water table has water that fills the tiny spaces (pores) between rock particles and the cracks (fractures) of the rocks.
Tuesday may 3 surface waters
The document discusses surface water and river systems. It defines key terms like watershed, which is the land drained by a stream, and tributary, which are streams that join the main river. It also describes the major components of a river system, including the source where the river begins, usually in highlands, the mouth where the river ends in the sea, and the drainage basin that is drained by the river and its tributaries.
Water
While the total amount of water on Earth remains constant, water is constantly moving around through the water cycle. Surface water, found in rivers, lakes, and streams, makes up only 0.25% of the total water on Earth but is extremely important for land animals and humans. Underground water, located deep below the Earth's surface and deposited over millions of years from rain and snow, also provides a supply of fresh water nearly anywhere on Earth.
Je 16 hydro.

G3 ppt
This document discusses different types of bodies of water including lakes, ponds, streams, rivers, reservoirs, tube wells, and springs. Lakes and ponds are inland bodies of standing or slowly moving fresh water that vary in size from small ponds to large lakes. Streams flow due to gravity and provide benefits like drinking water but can also erode rock. Rivers are larger bodies of flowing water that drain into oceans or other bodies of water. Reservoirs are bodies of impounded water created by dams to regulate water supply. Tube wells and springs tap into underground sources of water.
Hydrosphere
The hydrosphere describes all water on, under, and over the surface of a planet. The water cycle describes the continuous movement of water through different states and reservoirs on Earth through processes like evaporation and condensation. Surface runoff occurs when rain or snowmelt causes water to flow over the land rather than being absorbed by the soil.

( Freshwater Biomes & aqeous environments).pdf
Freshwater biology is the study of freshwater ecosystems and the relationships between organisms in freshwater environments and their physical and chemical surroundings. It seeks to understand freshwater biomes like rivers, ponds, lakes, wetlands, groundwater, and how living things interact in these environments. Freshwater biomes cover around 20% of the Earth's surface and contain a diversity of species, though they face threats from pollution and waste. The properties of freshwater, like its low salt concentration, allow unique plants and animals to thrive in freshwater ecosystems around the world.

Ponds are smaller bodies of standing freshwater than lakes. They are often shallow and contain plants, algae, and small aquatic animals. Ponds provide habitat for species like frogs, turtles, and fish. While ponds can be naturally occurring, human activities like roads and overgrazing can negatively impact ponds. The design of a pond determines what wildlife it will support. Ponds are used for aesthetic, agricultural, and wildlife purposes.
Words about water
The document defines and describes various bodies of water. It discusses seas as large expanses of salt water connected to oceans. Rivers are described as freshwater flows towards larger bodies of water. Ponds are smaller than lakes and hold standing fresh or salt water. Streams have currents confined within banks. Oceans are large bodies of saline water forming the hydrosphere. Puddles are small accumulations of liquid, usually water, on surfaces.

The document discusses water resources and their uses. It defines water resources as water sources that are useful to humans, including for agricultural, industrial, household, recreational, and environmental purposes. It provides examples of good uses of water resources like fixing leaks and taking shorter showers, and bad uses like long showers and washing cars with running water. The document proposes creating an awareness campaign for students about water conservation and improving water infrastructure to address wasting of water resources.
The Hydrosphere
The hydrosphere refers to all the water on, above, and below the Earth's surface, including oceans, lakes, rivers, groundwater, and water in the atmosphere. The water cycle transfers water between different states as it circulates around the Earth through processes like evaporation, condensation, precipitation, and collection. Water pollution threatens the hydrosphere when contaminants are introduced into bodies of water.

Earths water
This document discusses the distribution and movement of water on Earth. It begins by outlining several hypotheses for the origin of Earth's water, such as planetary cooling and volcanic activity. It then explains that 97% of the world's water is salt water in the oceans, 2% is frozen in ice caps and glaciers, 0.5% is non-consumable land water, and only 0.5% is freshwater available for human consumption. The document also describes the five major oceans - Pacific, Atlantic, Indian, Arctic, and Southern - and discusses factors like salinity, depth, and location. Additionally, it provides details on groundwater and freshwater resources like rivers, lakes, and the water cycle.
Waters on earth
The document discusses the origin and distribution of water on Earth. Most of Earth's water (97%) is found in the oceans, while 2% is frozen in ice caps and glaciers. A small percentage (0.5%) of freshwater is available for human consumption on land. The oceans contain salt due to minerals like sodium and chloride that are deposited from rivers and precipitation over time. Oceanographers study various aspects of the oceans like biology, geology, chemistry, and physics. They conduct field research, collect data, analyze samples, and produce findings to increase understanding of ocean processes and conditions.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.
